Referring now to FIG. 1, antenna component 120 can be configured toselect at least one segment of the one or more segments in response tothe at least one parameter. For example, and referring to FIG. 3,monitor component 110 can detect a power level of one or more signalsreceived via respective segments 310 _(A), 310 _(B), 310 _(c), and 310_(D) of communications device 300. If an orientation of communicationsdevice 300 changes, and/or at least one segment of segments 310 _(A),310 _(B), 310 _(C), and 310 _(D) are obstructed, one or more segments ofsegments 310 _(A), 310 _(B), 310 _(C), and 310 _(D) can experiencereduced signal transmission and/or reduced signal reception powerlevels.

In an aspect, the quality of the signal can include apower of the signal, a magnitude of the signal, or a direction ofpropagation of the signal. For example, the direction of propagation ofthe signal can be modified by control component 525, e.g., viatransmission component 530 described below, if transmission controlcomponent 525 selects segment(s) of the one or more segments that, e.g.,face a direction, or are within a wireless coverage angle, of anotherdevice wirelessly coupled to antenna segments 505 _(A), 505 _(B), etc.

In an aspect, control component 525 can be communicatively coupled to atransmission component 530, which can include components, hardware,devices, etc. configured to couple with one or moretransmitters/transceivers communicatively coupled to antenna segments505 _(A) and 505 _(B).

Further, antenna component 120, 520, etc. can beconfigured to select at least one segment of the one or more segments inresponse to the obstruction of the first segment. In one aspect, antennacomponent 120, 520, etc. can (1) decrease use of the first segment,e.g., turn the first segment off, reduce power consumption associatedwith the first segment, not utilize the first segment in wirelesscommunication(s), etc. and/or (2) increase use of the at least onesegment, e.g., turn the at least one segment on, increase powerconsumption associated with the at least one segment, utilize the atleast one segment in the wireless communication, etc. in response to theobstruction. In an aspect, the at least one segment can be associatedwith a higher level of signal recovery, or detected signal power,compared to the first segment.

In yet another aspect, antenna component 120, 520, etc. can beconfigured to (1) first modify, via the first segment, at least one of afirst power of a first signal, a first magnitude of the first signal, ora first direction of propagation of the first signal, in response to theobstruction; and/or (2) second modify, via the at least one segment, atleast one of a second power of a second signal, a second magnitude ofthe second signal, or a second direction of propagation of the secondsignal.

For example, antenna component 120, 520, etc. can reduce a transmissionpower of a signal transmitted via the at least one segment if the atleast one segment is not obstructed, and increase a transmission powerof another signal transmitted via the first segment if the at least onesegment is obstructed. As such, antenna component 120, 520, etc. canoptimally manage transmission power of a communications device whilereducing overall exposure to electromagnetic radiation, measured as aspecific absorption rate (SAR)—antenna component 120, 520, etc. canmaintain a constant (or near constant) SAR while reducing thetransmission power of the signal and increasing the transmission powerof the other signal.
